Brit Mag Study
There was a Brit bike magazine study on this same subject, only more in depth. I don't remember the details, since I just read it in the bookstore, but I know it involved Honda motorcycles of all types, utilizing just about every type of braking system, LBS, ABS, and no assist, all on wet tarmac. They used a CBR600, a Valkyrie (maybe a VTX or a Shadow), an Interceptor, and an X-11,maybe others. Like I said, it was about six months ago, and I don't even remember what magazine it was in - probably Ride, they're generally the most useful.
If anyone remembers the details of this test, you could fill my (substantial) gaps.
